Introduction: Clinician and pain researchers agree that there is a need for measures of pain. In pigs, being a species of prey, pain may be concealed and thus difficult to assess. However, identification of pain is necessary to enable its alleviation. Several physiological and behavioural parameters have been used in this respect during the last decades, however with only little success. A useful method must be able to distinguish pain-related changes from behaviours related to...

Introduction: In swine industry, piglets are tail docked at 3~7days old to prevent tail biting which is not fully understood what reason is. However, in the point of animal welfare, the cutting action is on negative perspective. Because the tail is a key role in communicating each pig and expressing their conditions, and docking practice causes amputation neuroma which is accompanied with pain. The aim of this survey was to examine the length and the diameter of docked...

Introduction: Fattening of entire male pigs as a consequence of changed legislation results in new challenges for the pork production. With regard to husbandry the question persists whether separate or mixed housing of male and female fatteners is the most appropriate. In this investigation, the effects of different housing regimes on social behavior, performance and boar taint were determined. Materials and Methods: For the field study, 1440 male and female...

I have a 40 acre farm in Ghana, West Africa which I am plannig of turning into a PIG production enterprise. I am actively seeking professional recommendations as how to commence the project on a industrial scale. My goal is to have a farm where i will produce and process to the market. These are the areas that i require suggestions: 1. the number of sow that i need to start a successful operation 2. modern design of housing for the pigs 3. the type of breed that will...

Introduction: The cross-contamination of non-medicated feed with residues of antimicrobials causes a public and animal health concern associated with the potential for selection and dissemination of resistance in commensal and potentially zoonotic bacteria. To identify the extent of the situation, we built a model that provides a way to estimate the percentage of cross-contaminated pig feed in total and per different levels at which cross-contamination may occur (i.e....

Introduction: In situ hybridization (ISH) is a nucleic acid-based method that allows the detection of a particular RNA or DNA sequence within the tissue sections. A novel ISH RNA-based chromogenic technique (RNAScope) describes single-molecule visualization through the use of hybridization-based signal amplification system. These characteristics make this platform a promising diagnostic approach, especially by improving sensitivities issues faced by classical ISH...

Introduction: The use of antibiotic drugs in food producing animals is considered to be a major risk factor for selection of antimicrobial resistance in humans as well as in animals. All antibiotics used in veterinary medicine are closely related to the antibiotics used in human medicine and may induce cross-resistance. Hence, minimizing antibiotic usage and prudent use of antibiotics are two key points to minimize the development of antibiotic resistance. Antibiotics...

Introduction: Climatic inadequacies may affect welfare and performance of pigs. The aim of this study was to evaluate the potential of running the heating system backwards during the summer with the aim to accomplish a more comfortable indoor climate. Materials and Methods: The study was made in herd with a module stable for fatteners with a natural mechanic ventilation system. Each unit had two pens sized 19.6 m 2 , out of which 5.7...

Introduction: Weaned piglets suffer many stressors such as sudden change of feed, change of pigs groups and passive protection decrease with ageing. The aim of this study was to investigate the effect of the inclusion of a free and buffered organic acids blend (OAs) to drinking water (DW) of weaned pigs on performance in presence or absence of medication to control enteric disease. Materials and Methods: One-hundred and forty (140) pigs in a conventional herd...

Introduction: Benchmarking has been widely practiced worldwide in the swine industry to improve farm management and productivity. Best practice benchmarking is defined as identifying those practices and processes associated with superior efficiency and performance. In the best-practice benchmarking for breeding farms, measurements in high-performing and ordinary farms have been used to provide values of target performance, using the 10th or 25th upper percentile of the...

Ten research projects have been funded as part of the Swine Health Information Center’s Wean-to-Harvest Biosecurity Program in collaboration with the Foundation for Food & Agriculture Research and the Pork Checkoff. Each project is designed to achieve the objectives of cost-effective, innovative solutions for a significant biosecurity gap in U.S. swine production. Institutions receiving awards in this first round of funding are Iowa State University, Carthage Veterinary Service,...

The Swine Health Information Center seeks a second round of research proposals to investigate cost-effective and innovative technologies, protocols, or ideas to enhance biosecurity during the wean-to-harvest phase of pig production, due April 28, 2023. Funding for the selected proposals will be provided by SHIC, the Foundation for Food & Agriculture Research, and Pork Checkoff as part of SHIC’s Wean-to-Harvest Biosecurity Program to be implemented over 2023-2024. The first round of...

Introduction: Although current evidence suggests a relatively low prevalence of MRSA in pigs in the USA, concerns remain about spread of multidrug resistance bacteria from the farm environment to swine workers and the wider community. The aim of this study was to characterize antibiotic resistance profiles of SA isolated from growing pigs in the USA. Materials and Methods: Twenty nasal swabs were collected from 36 growing pig sites in 11states in the USA,...

Introduction: Piglets from gilts have poorer performance and health during later life. The objective of this study was to evaluate the effect of sow parity and other lactation parameters on pig welfare lesions in the weaner and finisher stages. Materials and Methods: The study was conducted on a farrow-to-finish commercial farm. At birth, the sex and bodyweight (BW) of 847 piglets was recorded as well as the parity of their dam and the number of piglets born...

Introduction: Tail biting outbreaks rate among the major threats in pig production. To prevent or at least minimize tail biting docking is routine practice in Germany, although it contradicts the Council Directive 2008/120/EC. Many factors, like climate, general health status, stocking density, food and water supply and especially insufficient environmental enrichment have a major impact on the tail biting incidence. In the present study, a straw-filled rooting tower...

Introduction: Animal welfare, has been traditionally evaluated by measuring level of aggression and stress parameters. However, feeding behavior can also provide a valuable indication of comfort or stress for gestating sows in large groups, when fed with ESF systems. Materials and Methods: The study was conducted at Albesa-Ramadera a 3300 sow, Site 1 farm, based in Catalonia, Spain. The farm has large group gestation (128 to 175 sows per group) and utilizes...

Introduction: Tail biting is a global welfare problem in the pig industry leading to significant tail injury and potential carcass rejection. The temporal effects of such injuries and subsequent healing are presently unknown, although limb amputation in humans can lead to abnormal neural activity and decreased nociceptive thresholds. In order to evaluate potential sensitisation following tail damage, we created a model by surgical amputation of tails, and assessed mechanical...

Introduction: To evaluate the effects of removing antibiotics (AB) from the diet of 1st and 2nd stage weaner pigs on the performance of negative behaviours. Materials and Methods: Weaned pigs in a total of 12 groups of 35 pigs each, had in-feed AB removed (NO; n=6) or maintained in the diet (AB; n=6). Groups were observed 1 day/wk between 0900 and 1300h for 3x5min periods each and all occurrences of fights, head knocks, tail, flank and ear biting...
